Title: Process for the manufacture of vinyl-phosphonic acid
IPC: C07F9/38
Filed: 1960-10-27
Abstract: Vinylphosphonic acid is prepared by reacting vinylphosphonic acid dichloride directly with at least two molar proportions of water in the absence of a solvent at a temperature above 20 DEG C. but not exceeding 300 DEG C. The reaction may be started at a temperature in the range 20-100 DEG C. and the temperature gradually raised to a final temperature of 105-190 DEG C.  A polymerisation inhibitor is preferably used above 200 DEG C.  An inert gas may be passed through the reaction mixture during reaction. Preferably 2.01 to 2.8 molar proportions of water are used. A mixture of vinylphosphonic acid dichloride with vinylphosphonic acid may be used as starting material. The product may be neutralised with an oxide or hydroxide of an alkali or alkaline earth metal or an aqueous solution of such a base may be used in the reaction. Specification 858,057 is referred to.

Abstract: 1,004,956. Delivering measured quantities of liquid. W. D. HENDERSON. Sept. 20, 1963 [Oct. 16, 1962], No. 37041/63. Heading B8N. [Also in Division F1] A system for dispensing liquid, such as oil, beer, ice cream or ink, comprises a cylinder 1 having a piston 14 movable therein against a resilient force 17 and provided with a nozzle 5 in which a valve 6 is adapted to permit liquid to flow into the cylinder, the nozzle arranged to cooperate with a second nozzle 33 such that pressurized liquid is supplied from the second nozzle into the cylinder to move the piston against the resilient means, a stop 13 being provided for limiting the movement of the piston in order to determine the exact volume contained in the cylinder. The piston 14 is normally urged downwardly by a spring 17 until a closure member 16<SP>1</SP> closes a port 19 leading to the nozzle 5, the outlet in the latter being closed by the valve 6 under the action of a spring 8. In operation, upon the engagement of the nozzle 5 with the nozzle 33 of a supply oil container 30 pressurized by air fed therein through a valve 37, a projection 35 on the valve 6 engages with a valve 34 in the container nozzle thereby opening both valves so that oil flows into the cylinder 1 against the action of the spring 17. When the cylinder is full as determined by the abutment of the piston 14 with the adjustable stop 13, the dispensing cylinder is removed from the container and, by opening the valve 6,via a rod-and-handle 9, 10, the oil is dispensed. In the modification shown in Fig. 2a, the piston return spring 17 is dispensed with and the space 60 above the oil level 59 is pressurized with air via a valve 25. A counter 61 is attached to the piston 14<SP>1</SP> and a stop 27 is adjustably mounted on a sleeve 20 forming a guide for the valve rod 9<SP>1</SP>.
